Axial Tilt

[DoctorX]

The Earth is not the only body in the solar system with an axial tilt.

Also tilted are many other planets.

Venus 177.4 deg
Earth 23.43 deg
Saturn 26.73 deg
Uranus 97.77 deg
Neptune 28.32 deg
Pluto 119.61 deg

Perhaps we could discuss Bode's Law.

[ProfessorW]

Mania's Martian sister publication has a feature next month in the 25.2 Degree column discrediting Bode's Law. Apparently, the good Herr Bode couldn't distinguish between right and left and so his calculations are all to pot.

Well, then there's always Milankovitch Cycles.
